INVENTO CHARLES E. LINDSAY, 0F ALBANY, NEW YORK.

TRACK-LININ G JACK.

Specification of Letters Patent.

Patented Dec. 9, 1919.

Application filed June 3, 1919. Serial No. 301,403.

To all whom it mag concern.-

Be it known that I, CHARLES E. LINDSAY, a citizen of the United States, and a resident of Albany, in .the county of Albany and State of New York, have invented certain new and useful Improvements in Track- Lining Jacks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same;

My invention relates to improvements in devices for alining railroad tracks by the application of the power of a jack to the lateral movement of the track structure, with a minimum of effort and time, and a maximum of accuracy.

My invention has for its object to provide a device of this description which shall be suificiently powerful to accomplish the desired result, and in the correct way, and be simple, light and durable in construction.

The invention is illustrated by the accompanying drawing on which Figure 1 is a side elevation of the device and Fig. 2 is an end elevation of it; reference to which is made in the following description and claims.

The device consists of a tripod A, from the articulated apex of which is suspended by a hanger B, a jack C, the rack D of which is articularly connected at its lowest extremity to a triangular link E, and to one end of a push bar F, which is forked; the link E is also articularly connected to two of the legs G G of the tripod A and near the lower extremity thereof at S; the push bar F is also articularly connected at the opposite end U which is slotted, to the lower extremity of the third leg H of the tripod A.

The legs G Gr of the tripod A terminate at the lower extremity in curved blades K K the leg H of the tripod A has both ends forked to properly engage with the other members.

The jack G comprises a casing or frame C through which the rack D moves vertically slidably when actuated by the pawl L, which is hinged at O to the end of the lever N, which is pivotally attached to the casing or frame at P; the rack D is held notch by notch by the gravity pawl M, which is attached to the frame 0 at R.

In the operation of the device, the tripod A with its attachments, is placed in its proper relation to the railroad track at the point where the track is to be alined in a direction away from the device; the blades K K are firmly embedded in the ballast or roadbed, the pivot T being at its lowest position and the end U of the push bar F being in contact with the track rail V, which is fastened to the track tie W.

The lever N is then moved downward, the power being transmitted through the hanger B to the apex A and forcing the blades K K into the ballast or roadbed; the downward movement of the lever N results in the pawl L engaging in a notch in the rack D and moving it up until the pawl M engages a notch, when the lever N is raised until the pawl L engages another notch and the process is repeated until the desired results are attained.

The movement upward of the rack D causes the pivot T and the link E to rotate around the pivot S as a fulcrum or base and impart to the push rod F, a motion toward the track rail at an angle thereto, which will impart the vertical and lateral movement thereto necessary to loosen it in the ballast and move it laterally.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

, 1. In a track lining jack, the combination with the legs of a tripod, two of which are each provided with a blade for engagement in'the ballast or roadbed, of a push bar pivotally connected at its outer end to one leg of the tripod, links pivotally connecting its inner end to the other legs of the tripod, and a jack interposed between the tripod and said links, substantially as set forth.

2. In a track lining jack, the combination with a tripod, and a toggle joint connecting the legs of the tripod near their lower ends, of a jack pivotally connected to the upper portion of the tripod, and pivotally connected to the toggle joint, substantially as set forth.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

CHARLES E. LINDSAY.
